Aperture Science, a company at the frontier for developing advanced portal technology, artificial intelligence systems, and the finest shower curtains you will ever bear witness to. But where does the magic happen? Deep within one of Michigan's many fine salt mines, that's where. A facility where, even when overrun by an artificial super-intelligence, there is still hope ('hope' defined as a testing environment where living humans and machines co-exist, not defining, necessarily, hope for the most efficient testing environment). Within the main facility, the Sector for advanced artificial intelligence research has gone AWOL, and we have our best men ('men' defined as artificial maintenance spheres of unspecified gender and quantity, not defining, necessarily, humans who are men - who are alive) working on a solution. Hope lives on in Sector B.
The first three chambers made. They are not polished, especially the leap chamber with Arial Faith Plates.
